Title: Camera
Inventor: MASUDA HIDETOSHI
IPC: G03B17/00
Filed: 1990-08-02
Abstract: PURPOSE:To properly inform the abnormality of an action to a photographer and to rewind a film already photographed without complicated operation by starting the rewinding of the film by depressing a photographing button when the abnormality of the action of a lens for focusing is detected. CONSTITUTION:When abnormality occurs in even one action among the photographing actions, an H level is outputted by an abnormal action detection means 5. The outputted signal thereof is outputted to a switch input circuit 1 and an external display means 8. As the result, all of operation buttons except the photographing button 7 among the operation buttons inputted to the circuit 1 cannot be detected by a CPU 2 and the photographing action as a camera is not executed at all. Besides, the display means 8 executes alarm display to the photographer when it receives the H level of the abnormal action from the detection means 5. When the photographing button 7 is depressed to the photographing position under such a state, both outputs of AND gates 11 and 12 become an L level and the same state that a rewinding button is operated at the time of a normal action is attained. In such a way, when the photogra pher executes the photographing by operating the photographing button no matter how the action of the camera is abnormal, the rewinding action of the film is started by a film feeding means 6.

Title: Overload protecting method of power amplifier
Inventor: YOSHIDA TETSUO
IPC: H04B1/04
Filed: 1984-10-03
Abstract: PURPOSE:To attain protection without stopping an output to mismatched load by using a signal from a control circuit so as to stop a part of plural power amplifiers. CONSTITUTION:An output of amplifiers 10 and 11 is synthesized by a synthesizer 12 and a power is applied from an output terminal 5 via a reflection detecting circuit 13. When the load impedance is fluctuated and the reflection is increased, a signal by a control circuit 14 stops any of the amplifiers 10 and 11. The stop control is applied simultaneously to terminals 28 and 32. Since a stopped power amplifier is not excited, the output impedance is high and a modulation switching circuit 25 is kept off and then the output of the power amplifier is not limited until the power supply voltage. When only one power amplifier is stopped, a part of the output or reflection is consumed in an isolation resistor. As a result, the load mismatching of the power amplifier in operation is reduced.

A motion compensation processing section 2 detects a retrieval block based on preceding frame data stored in a frame memory FM 2. A difference processing section 3 makes differential arithmetic operation between the input macro block and the retrieval block and an arithmetic operation section 4 calculates a difference absolute sum. A motion discrimination section 6 compares the difference absolute sum and a predetermined threshold level to discriminate the motion picture. When the motion of the picture is a predetermined value or over, the picture is sent to a picture compression processing section B compressing input frame data and sending the data.

Title: Light path bend mirror and optical pickup using it
Inventor: IIZUKA GENICHI
IPC: G11B7/135
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of coma aberration by setting a light transmission surface so that its light path lengths become nearly equal related to all areas of a spot of a light beam transmitting through mold resin. SOLUTION: The light beam from a semiconductor laser element 22c in a light receiving/emitting device 22 is tilted slightly, by a slope angle θ2 of e.g. 6 degree related to a horizontal direction by being reflected at an acute angle by its inner surface 23b while being made incident on the optical path bend mirror 23 and outgoing from that. On the other hand, the outgoing surface 23c of the light path bend mirror 23 is tilted by a taper angle θ1, e.g. 6 degree since it has a mold removing taper at a molding time. Thus, since the light beam transmitting through an incident surface 23a, an inner surface 23b and the outgoing surface 23c in the bend mirror 23 becomes a nearly equal optical path length in all areas of its spot, the coma aberration is not caused.

Title: Solid electrolyte battery
Inventor: NAGAI TATSU
IPC: H01M6/18
Filed: 1981-12-21
Abstract: PURPOSE:To decrease internal resistance and increase discharge performance by forming a cathode on one side of a solid electrolyte, and an anode comprising lithium or lithium alloy through a thin layer of metal halide on the other side of  the solid electrolyte. CONSTITUTION:A thin layer 3 comprising metal halide decreases interface resistance between an electrolyte 1 and an anode 4, and that results in good discharge performance. The metal halide is typically LiX (X is halogen) and metal halide other than lithium such as Pb, Sn, or Al is also included. The metal halide other tan LiX reacts with Li immediately after assembling a battery to form LiX. This functions as Li ion conductor, and a metal by-product such as Pb, Sn, or Al alloys lithium to function as an Li ion conductor. Therefore, the metal halide fills gaps between the anode 4 and the solid electrolyte 1 without giving an adverse effect on discharge reaction of Li<+> ion, and interface resistance is decreased.
